[0022] Example

[0023] refer to Figures 1 to 4 This embodiment of a gas ignition gun that is easy to ignite includes an ignition gun body 1, an installation kit 2 is fixedly installed at the output end of the ignition gun body 1, and a telescopic tube 3 is fixedly installed inside the installation kit 2.

[0024] The telescopic tube 3 includes a sleeve 31, which is fixedly connected to the inside of the mounting kit 2. An inner sliding tube 32 is slidably connected inside the sleeve 31. An ignition tube assembly 33 is fixedly installed at the outer end of the inner sliding tube 32. An elastic friction-enhancing rubber ring 34 is fixedly connected to the outer surface of the inner sliding tube 32. The outer surface of the elastic friction-enhancing rubber ring 34 is in close contact with the inner wall of the sleeve 31. During the application of this device, the ignition gun body 1 is first held in the hand, and the length of the telescopic tube 3 is adjusted according to the required ignition distance. The mounting kit 2 is fixed to the output end of the ignition gun body 1 to provide a mounting base for the telescopic tube 3. The sleeve 31 of the telescopic tube 3 is fixed to the mounting kit. 2. Inside, the inner sliding tube 32 is slidably connected to the inside of the sleeve 31. When the operator pulls the ignition tube assembly 33 at the outer end of the inner sliding tube 32, the inner sliding tube 32 slides along the inside of the sleeve 31. The elastic friction-enhancing rubber ring 34 on the outer surface of the inner sliding tube 32 fits tightly against the inner wall of the sleeve 31 due to its own elasticity, increasing the friction between the two and allowing the inner sliding tube 32 to stay stably at any position, thereby adjusting the length of the telescopic tube 3. After adjustment, the ignition tube assembly 33 can be used for ignition operation at the set length. After use, the ignition tube assembly 33 is pushed, and the inner sliding tube 32 slides inward along the sleeve 31 to retract, shortening the overall length of the ignition gun for easy storage and carrying.

[0025] refer to Figures 2-4The ignition tube assembly 33 includes an outer ignition tube 331, which is fixedly installed at the outer end of the inner slide tube 32. Inner brackets 332 are fixedly connected to both sides of the outer end of the outer ignition tube 331. An ignition nozzle 333 and a conductive needle 334 are fixedly connected to the two inner brackets 332 respectively. The end of the conductive needle 334 is located at the output end of the ignition nozzle 333, and the input end of the conductive needle 334 is provided with a wire 335. The input end of the conductive needle 334 is electrically connected to the pressure ceramic igniter inside the ignition gun body 1 through the wire 335. A flexible hose 336 is fixedly connected to the input end of the ignition nozzle 333, and the input end of the ignition nozzle 333 is connected to the valve output end of the fuel tank through the flexible hose 336. During the application of this device, when the ignition tube assembly 33 is working, the outer ignition tube 331... Fixed to the outer end of the inner slide tube 32, the position is adjusted with the extension and retraction of the inner slide tube 32. The two inner brackets 332 at the outer end of the ignition outer tube 331 respectively fix the ignition nozzle 333 and the conductive needle 334, ensuring that the end of the conductive needle 334 is in the corresponding position of the output end of the ignition nozzle 333. After the length of the telescopic tube 3 is adjusted, the piezoelectric ceramic igniter inside the ignition gun body 1 supplies power to the conductive needle 334 through the wire 335. The end of the conductive needle 334 generates an electric spark. At the same time, the valve of the oil tank is opened, and the combustible gas is delivered to the ignition nozzle 333 through the hose 336 and sprayed out from its output end. It is ignited by the electric spark generated by the conductive needle 334, completing the ignition operation. The hose 336 and the wire 335 extend and retract accordingly with the movement of the inner slide tube 32 to ensure the continuity of gas delivery and power transmission.

[0026] refer to Figures 2-4 The flexible hose 336 and the wire 335 are fixedly connected to the outer surface of the end of the mounting kit 2 with an elastic contraction assembly 35. The elastic contraction assembly 35 is fixedly connected to the inside of the sleeve 31. The elastic contraction assembly 35 includes a telescopic spring 351, which is fixedly installed inside the sleeve 31. A connecting ring 352 is fixedly installed on the outer end of the telescopic spring 351. The flexible hose 336 and the wire 335 are both fixedly connected to the inner side of the connecting pipe. The outer surface of the ignition outer tube 331 is provided with ignition holes 337 at equal intervals. The corners of the outer surface of the ignition gun body 1 are all rounded. During the application of this device, when the ignition gun is working, the flexible hose 336 and the wire 335 are close to the outer surface of the mounting kit 2 with an elastic contraction assembly 35. The outer surface of the end is connected to the elastic contraction assembly 35 via a connecting ring 352. The telescopic spring 351 of the elastic contraction assembly 35 is fixed inside the sleeve 31. When the inner slide tube 32 drives the ignition tube assembly 33 to extend or retract, the telescopic spring 351 stretches or retracts accordingly. The connecting ring 352 forms a tension force on the hose 336 and the wire 335 to prevent them from getting tangled and ensure stable gas delivery and power transmission. The ignition hole 337 on the outer surface of the ignition outer tube 331 can assist flame diffusion and improve ignition efficiency. The rounded corners on the outer surface of the ignition gun body 1 can reduce bumps and damage during use and enhance safety. These structures work together with other components to ensure that the ignition gun works stably and efficiently.

[0027] Operating principle and advantages: During application, this device first allows for adjustment of the length of the telescopic tube 3 according to the required ignition distance. When the operator pulls the ignition tube assembly 33, the inner sliding tube 32 slides along the inside of the sleeve 31. The elastic friction-enhancing rubber ring 34, due to its own elasticity, fits tightly against the inner wall of the sleeve 31, increasing the friction between them. This allows the inner sliding tube 32 to remain stably in any position, achieving the adjustment of the telescopic tube 3 length. During this process, the telescopic spring 351 of the elastic contraction assembly 35 is stretched, generating tension that pulls on the connecting ring 352, thereby tensioning the hose 336 and the wire 335, maintaining the stability of the hose 336 and the wire 335, and preventing them from becoming tangled or misaligned. After adjustment, ignition is performed. The control components of the gun body 1 include a piezoelectric ceramic igniter inside the ignition gun body 1. Current is transmitted to the conductive needle 334 via wire 335. Simultaneously, the fuel tank valve opens, and combustible gas is delivered to the ignition nozzle 333 via hose 336. The combustible gas is ejected from the output end of the ignition nozzle 333. An electric spark is generated at the end of the conductive needle 334 at the output end of the ignition nozzle 333, igniting the ejected combustible gas. The ignition hole 337 on the outer surface of the ignition outer tube 331 assists in flame diffusion, facilitating ignition. The inner bracket 332 fixes the ignition nozzle 333 and the conductive needle 334, ensuring their relative position is stable and guaranteeing ignition reliability. After use, the ignition tube assembly 33 is pushed, and the inner sliding tube 3... 2. The telescopic tube 3 retracts inward along the sleeve 31. At this time, the telescopic spring 351 retracts under its own elastic force, driving the connecting ring 352 to move synchronously, continuing to tension the hose 336 and the wire 335, so that they are orderly stored with the retraction of the inner sliding tube 32. The outer surface of the ignition gun body 1 has rounded corners to reduce bumps and damage during use. During the application of this device, its telescopic tube 3 consists of the sleeve 31 and the inner sliding tube 32. The inner sliding tube 32 can slide along the sleeve 31. With the friction positioning of the elastic friction-enhancing rubber ring 34, the extension length of the ignition tube assembly 33 can be adjusted according to the ignition requirements to meet short-distance and long-distance ignition scenarios, reducing the danger of close-range operation. When not in use, the inner sliding tube 32 can be... The gun retracts into the sleeve 31, shortening the overall length of the ignition gun and solving the problem of inconvenient storage and carrying caused by the fixed barrel of traditional ignition guns. The inner frame 332 fixes the ignition nozzle 333 and the conductive needle 334, ensuring that the end of the conductive needle 334 accurately corresponds to the output end of the ignition nozzle 333, so that the electric spark can reliably ignite the combustible gas. During the adjustment of the extension and retraction of the elastic retraction group 35, the telescopic tube 3 maintains the stability of the hose 336 and the wire 335 by pulling and tightening them, avoiding tangling and ensuring the stability of gas delivery and circuit connection. The ignition hole 337 of the ignition outer tube 331 assists in flame diffusion and improves ignition efficiency. The rounded corners of the ignition gun body 1 reduce accidental bumps and damage during use.The elastic friction-enhancing rubber ring 34 stabilizes the position of the telescopic tube 3, preventing sudden slippage during use and affecting operational safety. The design of the telescopic spring 351 and connecting ring 352 of the elastic contraction group 35, through the tensioning effect on the hose 336 and the wire 335, ensures that both remain in an orderly state during the extension and retraction process, adapting to the working requirements under different extension lengths and extending the service life of the components.

[0028] The lighter body 1 has an internal oil tank and a ceramic igniter. The wire 335 is electrically connected to the ceramic igniter, and the hose 336 is connected to the valve of the oil tank. The elastic friction force formed by the elastic friction ring 34 is much greater than the extension force of the telescopic spring 351. Even when the telescopic spring 351 is in a stretched state, its elasticity cannot pull the inner slide tube 32 of the elastic friction ring 34. Therefore, it can be kept from retracting after being extended. The lighter body 1 is a prior art, and its internal structure has been disclosed and applied in the prior art. The improvement point of this application is not in the internal structure of the lighter body 1. Therefore, the internal structure of the lighter body 1 will not be described in detail.
